Yarn splicing guide device of automatic bobbin winder

Abstract

The invention discloses a yarn splicing guide device of an automatic bobbin winder. The device comprises a splicer and a guide bracket, wherein the splicer is used for grabbing a large suction nozzle at the upper yarn end and grabbing a small suction nozzle at the lower yarn end, and the guide bracket keeps a fixed position with the splicer; the guide bracket supports a yarn guide hook in a swing mode, and the yarn guide hook is mutually and fixedly connected with a guide swing arm; the yarn guide hook and an upper yarn passage form space intersection, and an arm end part of the guide swing arm is positioned on a rotary track of the small suction nozzle; and the guide bracket is also provided with an offsetting spring for rotating and offsetting the yarn guide hook. The yarn guide hook is mutually and fixedly connected with the guide swing arm through a connecting sleeve which is sleeved on a yarn guide hook support shaft in a swing mode; the yarn guide hook support shaft is vertically and fixedly arranged on the guide bracket; and the yarn guide hook and the guide swing arm are crossed and staggered in space. The yarn splicing guide device has the advantages of simple structure, accurate yarn guide and good splicing quality, and is widely applied to various automatic bobbin winders.

Description

technical field [0001] The invention relates to a post-processing equipment of spinning machinery, especially an automatic winder used in the winding process, in particular, it guides the yarn to the splicing channel when the automatic winder performs yarn splicing s installation. Background technique [0002] The winding process is an essential process in the spinning process. After the winding process, not only can the spun bobbin be wound into bobbin yarn, so that it can be used in the subsequent process, but also the yarn impurities can be effectively removed during the winding process. And defects, improve yarn quality. Most of the traditional winding equipment use manual joints, the quality is unstable, labor intensity and manpower consumption are large; while the automatic winding machine has the advantages of high efficiency, high speed and high quality, the automatic winding machine replaces the traditional winding machine is a modern production inevitable require...

Problems solved by technology

This mechanism solves the coordination problem between the small suction nozzle and the yarn catcher, and greatly simplifies the transmission mechanism. When the position is above the splicer, there is a large space distance between it and the splicer and the upper yarn guide plate of the splicer, and at the same time, the guiding force point of the yarn catcher for the upper yarn is not in the splicing channel area of ​​the splicer , the joint effect of the above two makes the yarn catching hook to introduce the upper yarn into the splicing channel, and it is necessary to "over-guid" the yarn for a long distance, and the yarn catching hook must slide a long dista
